Troubleshooting Monitor Accuracy Issues

Understanding False Alert Scenarios

Monitoring discrepancies can occasionally occur when external factors interfere with our scanning processes. These situations typically manifest as incorrect downtime alerts whilst your service remains operational, or conversely, missed outages when genuine problems exist.

The following guidance addresses the most prevalent causes behind monitoring inconsistencies and provides actionable remedies to restore reliable oversight of your digital assets.

Infrastructure-Level Access Restrictions

Web hosting environments frequently implement security measures that inadvertently block automated monitoring requests. These protective systems may interpret our regular health checks as suspicious activity, resulting in blocked connections and erroneous downtime notifications.

Resolution approach: Contact your hosting provider's technical support team to whitelist our monitoring IP addresses. Explain that PulseStack™ performs legitimate uptime verification services and requires unrestricted access to accurately assess your website's availability.

Server-Side Security Barriers

Firewall configurations and security plugins can create additional layers of protection that prevent our monitoring systems from reaching your endpoints. This commonly affects WordPress sites utilising security plugins or servers with restrictive firewall policies.

Recommended actions:

Review your server's firewall configuration and add our IP ranges to the permitted list
Check security software settings (such as WordPress security plugins) and configure them to allow PulseStack™ monitoring requests
Ensure that monitoring traffic isn't being filtered or rate-limited by protective systems

Caching and Response Method Complications

Content delivery networks and caching systems sometimes serve outdated versions of your site to our monitoring agents, creating a disconnect between actual availability and reported status. Additionally, some server configurations respond differently to HEAD requests compared to standard browser GET requests.

Solutions to implement:

Utilise our cache-busting functionality to force fresh content retrieval during monitoring checks
Configure your server to handle HEAD requests identically to GET requests
For Professional plan subscribers: switch monitoring method from HEAD to GET requests in your monitor configuration

Heartbeat Monitoring Timing Issues

Scheduled task monitors depend on receiving regular signals from your systems within specified timeframes. Delays or failures in transmission can trigger false downtime alerts even when your processes are functioning correctly.

Verification steps:

Confirm that your scheduled tasks are successfully transmitting signals to PulseStack™ endpoints
Verify that requests arrive within the configured grace period
Ensure you're using supported HTTP methods (POST or GET) for heartbeat communications

Quick Resolution Techniques

When standard troubleshooting approaches prove insufficient, simple operational resets often restore proper monitoring functionality. Consider pausing and restarting your monitor configuration to clear any temporary system states that might be affecting accuracy.
